4. The communication apparatus according to claim 3 , wherein the instructions, when executed by the one or more processors, further cause the communication apparatus to act as a change unit configured to change a parameter of the data communication application, wherein, in a case where the notification unit notifies the warning, the change unit changes the parameter of the data communication application.

5. The communication apparatus according to claim 4 , wherein, when the change unit changes the parameter of the data communication application, the notification unit notifies information about change of the parameter.

6. The communication apparatus according to claim 4 , wherein the change unit changes the parameter of the data communication application based on an instruction from outside.

7. The communication apparatus according to claim 1 , wherein the communication unit performs in parallel the first communication and the second communication using an evolved-universal terrestrial radio access (E-UTRA)-new radio (NR) dual connectivity function.

8. The communication apparatus according to claim 1 , wherein the instructions, when executed by the one or more processors, further cause the communication apparatus to act as further comprising a transmission unit configured to transmit a signal to request off-setting of the E-UTRA-NR dual connectivity function to a core network of cellular network communication, wherein, in a case where the notification unit notifies the warning, the transmission unit transmits the signal to request the off-setting.

9. The communication apparatus according to claim 1 , wherein a first base station is a base station for long term evolution (LTE) communication, and a second base station is a base station for 5th generation mobile communication system (5G) communication.

10. The communication apparatus according to claim 1 , wherein the first wireless communication method is a wireless communication method conforming to the LTE, and the second wireless communication method is a wireless communication method conforming to the 5G.

11. The communication apparatus according to claim 1 , wherein the communication unit performs in parallel the first communication and the second communication, to upload data to a server through a first base station using the first wireless communication method and a second base station using the second wireless communication method.

12. The communication apparatus according to claim 1 , wherein the warning notifies the user that communication is difficult in a case where communication is difficult.

13. The communication apparatus according to claim 1 , wherein the warning notifies the user that dual connectivity communication is difficult in a case where dual connectivity communication is difficult.

14. The communication apparatus according to claim 1 , wherein the warning notifies the user that communication is unavailable in a case where communication is unavailable.

15. The communication apparatus according to claim 1 , wherein the warning notifies the user that dual connectivity communication is unavailable in a case where dual connectivity communication is unavailable.

16. The communication apparatus according to claim 1 , wherein the warning notifies the user that communication is disconnected in a case where communication has become disconnected.

17. The communication apparatus according to claim 1 , wherein the warning notifies the user that dual connectivity communication is disconnected in a case where dual connectivity communication has become disconnected.

18. The communication apparatus according to claim 1 , wherein the warning notifies the user that at least one of real-time moving image communication and high-speed communication is or may be difficult in a case where dual connectivity communication is difficult or has become disconnected.

19. A method of controlling a communication apparatus, the method comprising: performing in parallel a first communication using a first wireless communication method conforming to 3GPP standard and a second communication using a second wireless communication method conforming to the 3GPP standard; acquiring a radio wave state in at least one of the first communication and the second communication while the first communication and the second communication are performed in parallel; outputting to a user a warning in a case where the first communication and the second communication are not performable in parallel due to the radio wave state; and determining whether a predetermined data communication application is under execution by the communication apparatus, wherein, in a case where the determining determines that the predetermined data communication application is not under execution, the communication apparatus does not output to the user the warning.

20. A non-transitory computer-readable storage medium storing a program to cause a computer to execute a method, the method comprising: performing in parallel a first communication using a first wireless communication method conforming to 3GPP standard and a second communication using a second wireless communication method conforming to the 3GPP standard; acquiring a radio wave state in at least one of the first communication and the second communication while the first communication and the second communication are performed in parallel; outputting to a user a warning in a case where the first communication and the second communication are not performable in parallel due to the radio wave state; and determining whether a predetermined data communication application is under execution by the communication apparatus, wherein, in a case where the determining determines that the predetermined data communication application is not under execution, the communication apparatus does not output to the user the warning.
